I would go with HKS for the speed loader. For factory holsters I like safariland, but galco makes really good off the shelf stuff as well. Grips are a personal thing, I like wood square buts on a shorter barrel k or l, and target grips on a longer barrel. I would not recommend a shoulder holster for most purposes. A good belt holster, with a good belt is quicker, more concealable, and more comfortable in most situations.
